IMPROVEMENT IN STOVE-PLATFORMS Specification forming part of LettersPatent No. 178,9 [7, dated June 20, 1876; application filed March 13,1876.

To all whom it may concern:

Be it known that I, JOHN WHEELER EL- LIOT, of the city of Toronto, inthe county of York and Province of Ontario, have invented an ImprovedBase Plate for Stoves, which improvement is fully set forth in thefollowing specification, reference being had to the accompanyingdrawings.

My invention consists of a cast or sheet metal plate molded or wroughtto a form which may be described the frustum of a shallow cone,surrounded atv the base by a raised rim, and provided with suitablepockets for the receipt of the toe of the stove-legs.

The said plate is elevated above the floor a suitable distance by feeteast or attached to the under side, with the object of permitting thepassage of a current of air induced by the heat of the stove underneathand out through the crown of the plate. Over the central opening of theplate, elevated and supported at a suitable height therefrom, aninverted conical crowning-plate is placed as an ornament, and with theobject of directing and assisting the circulation of the air-current.

In the accompanying drawing, Figure 1 is a sectional side elevation, andFig. 2 a half plan, of a base-plate constructed according to myinvention.

A is the lower part of an ordinary heatingstove, supported on the legsB, in the usual way. 0 is the base-plate, raised above the level of thefloor by the feet O, and 1nanu- 'factured from east or sheet metal, butpreferably from the former. The center of the plate is raised above themargin and perforated, the opening D being provided to admit the upwardpassage and circulation of the air induced by the heat of the stove.

This opening is crowned with an inverted conical plate, E, at a suitableheight above the top of the plate to admit the free outward passage ofthe air. From the interior of the base-plate F is a raised ornamentalrim, which may or may not be provided, as desired, but which, whenadded, greatly improves the tinish of the plate. G are pockets designedto receive and firmly secure the feet of the stove.

The object of my invention is to cause an equal distribution of heat inapartments by inducing a circulation under the lower part of the stove.In many descriptions of stoves much ot' the heat generated is lost fromthe fact that heated air always ascends, the lower portion of theatmosphere, especially that next the floor in an apartment, remainingcold long after the upper part has been thoroughly warmed. With mybase-plate the air within the interior of the plate is rarefied by theheat of the stove, and is forced by lateral pressure of the surroundingcold air out of the opening in the crown of the plate, as shownby-arrows. This action being continuous as long as heat remains in thestove, a

constant current or circulation of air in the lower part of the room isinduced and maintained until the wholeatmosphere is of the same degreeof heat, and at the same time the floor immediately under the plate isprevented from being heated too much.

I do not claim, broadly, a platform or baseplate of a stove having anair-chamber, as described but What I do claim as original, and desire tosecure by Letters Patent, is

The centrally-pertorated base-plate O, shaped as described, and providedwith an elevated deflector, E, and foot-sockets G, as and for thepurpose specified.
